Telecom systems and ISP people were also astonished, as it is quite normal for core switching and routing equipment to have a very limited write endurance solid state boot and OS storage device. For a long time very serious $300,000+ routers booted off compact flash cards, back in the day.
Yep. I worked on those myself and participated in the usual pre-DVT destructive testing of our embedded flash devices specifically to count core dumps and config commits that the device could survive..
